Microwave Magnetron 2M211A-M2R (№22)

Magnetron for Panasonic Microwave Oven 2M211A-M2R (Position No. 22)

The Heart of Your Microwave: Original Power and Flawless Heating

Is your microwave spinning the plate, turning on the light, and buzzing, but leaving your food cold? The root cause of this behavior is typically a faulty magnetron—the core emitter of high-frequency waves.

We offer the genuine Panasonic 2M211A-M2R magnetron—a highly reliable vacuum electron device engineered specifically to restore the factory-spec performance of your microwave oven. This is not just a compatible replica; it is a certified part that will bring back your appliance's original heating speed and uniformity.

High-End Technical Specifications

The 2M211A-M2R magnetron is engineered to meet stringent thermal regulation and frequency stability requirements:

• Model / Marking: 2M211A-M2R

• Factory Diagram Number: position No. 22 (according to official Panasonic service manuals)

• Operating Frequency: 2460 MHz (the standard for rapid excitation of water molecules in food)

• Power Output: 700–800 W (the optimal balance between energy efficiency and cooking speed)

• Cooling Type: air-cooled (radiator fins with a high heat dissipation coefficient)

• Mounting Design: standard mounting flanges (lugs) for quick and secure installation in the chassis

• Airflow and Terminal Direction: the power connector orientation is designed for standard, tension-free routing of high-voltage wiring.

Full Compatibility with Panasonic Models

This specific magnetron modification is the factory-installed part for several of the most popular 20-liter Panasonic microwave ovens:

• Panasonic NN-SM330W (a classic solo model with mechanical controls)

• Panasonic NN-GM340W (a reliable model featuring a grill function)

Expert Technician Tip: since the 2M211A-M2R magnetron features standard power parameters and mounting specs, it can also be used to replace similar magnetron assemblies in microwave ovens from other brands (such as LG, Samsung, or Whirlpool), provided that the mounting configuration and the direction of the power terminals match.

Advantages of the Original 2M211A-M2R Magnetron

By choosing an original spare part over cheap, unbranded replicas, you ensure:

1. Appliance and Family Safety: The genuine magnetron features a perfectly sealed vacuum block and a premium antenna cap. This completely prevents arcing, mica sheet burnout, and subsequent damage to the high-voltage transformer or diode.

2. Maximum Efficiency: due to precise microwave focusing, energy is not wasted on heating the oven cavity itself but is entirely directed at the food.

3. Durability: stable cathode emission and heat-resistant ceramics guarantee 7–10 years of trouble-free operation, provided the microwave is used according to instructions.

4. Quiet Operation: the proprietary build quality minimizes the resonant hum when the magnetron starts up under high voltage.

Signs That Your Magnetron Needs to Be Replaced:

• The microwave turns on and the timer counts down, but the food remains completely cold.

• A loud, unusual buzzing, humming, or crackling noise occurs when the heating cycle starts.

• Sparks or visible electrical arcing appear inside the cavity (usually near the right wall where the mica sheet is located).

• The magnetron itself shows signs of overheating (discolored metal), cracked magnets, or a burnt-through metal antenna cap.

Safety and Installation Guidelines

WARNING! IMPORTANT! A microwave oven is a high-hazard appliance. Even after being unplugged from the wall outlet, the high-voltage capacitor retains a charge of up to 4000 Volts. It is strongly recommended that you leave magnetron replacement to a qualified service engineer.

Before installing the new part, make sure to check:

• The integrity of the mica sheet (if it is burnt or damaged, it must be replaced along with the magnetron; otherwise, the new part will fail prematurely).

• The condition of the high-voltage diode and the fuse.

Restore your microwave to its original power! Order the genuine 2M211A-M2R magnetron today and enjoy hot meals again without the expense of buying a brand-new appliance.
